One set of wood parts cut to size for wooden generator. Includes 4 flat pieces of about 1" x 3" (2cm x 8cm) for sides and 2 flat square pieces about 3.5" x 3.5" (8cm x 8cm) for the top and bottom. Also includes a 3.5" long wood dowel with 1/2" hole (for magnet).

This simple switch can be used for all low voltage applications. It is a double blade switch; so, it connects or disconnects two circuits simultaneously. Mount it on any project board or wooden board using a pair of wood screws.

This small generator (Dynamo)may be mounted on a bicycle to produce electricity. The turning tires will turn the head of the generator and it will produce electricity that is accessible from the bottom contact.

Electricity produced by this generator can be used to light up multiple light bulbs.

Combination set of magnesium electrodes includes 2 flat electrodes and 2 coil electrodes made of high purity magnesium metal. Flat electrodes are stamped with letters Mg to identify the electrode type.

Magnesium electrodes may be a valuable addition to your collection of metals.

This set contains the essential materials used in construction of a simple electric circuit that can light up a light bulb. It includes a battery holder, switch, lamp holder, light bulb, connecting wires and a wooden board.

Piezoelectric earphones also known as crystal earphones are the most sensitive earphones. In fact they are at least 10 times more sensitive than very sensitive magnetic earphones, dynamic earphones, and electrostatic earphones. Sensitive earphones have a very high impedance, which is measured in ohms.

Crystal Earphones are used in the construction of the crystal radio and in some science experiments such as listening to electric fish.

Short banana jack is a panel-mount socket for 4mm banana plugs with any length. Can be mounted on metal surfaces with up to 1 mm, and plastic or wood surfaces with up to 4 mm thickness. It mounts on a 8mm hole. The overall length is 13 mm. The face outer diameter is 11 mm.

Constructing a wooden electric generator is one of the best ways to learn the principles of electric generators. Completed kit is about 4 inches long and 2 inches wide. The wood dowel axle is about 4 inches long.

Battery Life Test Kit includes essential materials and online instructions to assemble a basic electric circuit to test general purpose alkaline (dry cell) batteries.
Kit includes four battery holders, four lamp holders, 10 light bulbs, mounting board and enough screws.
You can use it to compare the life of AA batteries and record your data and make a bar chart.

Similar to the game you may have seen at the carnivals, this kit allows you to customize your own fun design which also makes it an intriguing educational tool. Also known as the steady-hand, buzz-wire, buzz-it and buzzer wire game.

Making electricity from chemicals is based on the same scientific principles
on which all modern batteries work.
You insert copper and zinc electrodes in an acidic liquid and produce
some electricity from the chemical reaction between your electrodes and
electrolyte.

This project will help students to learn about producing electrical energy using chemical energy.

Bicycle generator with metal mount is a standard size electric generator mountable to the back wheel or front wheel of bicycles. It can also be used to generate electricity in high speed home-made water mills or windmills.

Banana plug, consisting of a cylindrical metal pin about 20 mm long, with a diameter of 4 mm, which can be inserted into a matching 4 mm socket to make an electrical contact. The pin has one or more lengthwise springs that bulge outwards slightly. These press against the sides of the socket, improving the electrical contact and preventing the pin from falling out. The back end of the banana plug is a color coded plastic insulator that may be red or black.

This is a metal battery holder that holds one D cell battery. This battery holder has two Fahnstock clips for easy connection of any solid wires from 22 AWG up to 14 AWG. This battery holder does not have any specific direction for inserting the battery. You have a choice to decide which end you would want to be positive and may reverse it as needed.

Warning: To prevent battery from overheating and subsequent discharge, turn the Fahnstock clips upward so they are not touching the metal frame.

This simple switch is used by students to make electrical circuits. This quality knife switch is perfect for science projects and electronic experimentation. With its predrilled holes, it can easily be mounted on any wooden surface or project board. Because of the open structure of the switch, you can visually determine if the circuit is closed or open.

Long Banana Jack is a panel-mount socket for 4mm banana plugs with up to 20 mm (1 inch) long pin. Can be mounted on metal surfaces with up to 2 mm, and plastic or wood surfaces with up to 5 mm thickness. It mounts on a 8mm hole. The overall length is 25 mm.

Low voltage buzzer works with 1 volt up to 4.5 volts DC.
An essential electrical part for use in physics, electrical circuits, sound experiments, and other general lab use. Strong plastic construction.

Used to study electromagnetic induction & transformer principles. The outer coil is about 50 mm tall and 32 mm in diameter. The inner coil is about 58 mm tall and 19 mm in diameter. The removable steel core with handle is 10 mm in diameter and 67 mm tall. All coils are wrapped with magnet wire with insulated binding posts as connectors. (New Version. Smaller size. Includes tutorial, instructions and suggested experiments.)

For use with electrovoltaic cells or in various other chemical, physics and electricity experiments.
Each metal electrode measures about 5" x 3/4" x 3/64" ( It is 12cm x 2cm x 1.2 mm in metric system).
Carbon (graphite) is 5 mm (1/8") thick.
This is the second most complete collection of metals offered by MiniScience. All metal electrodes are stamped with 2 letter identification code for easy identification.WARNING: Metal electrodes have sharp edges and can cause injury. Not a toy!. Handle with care.

This standard lamp socket is available in Black or White, this miniature light socket or lampholder is perfect for that electronics
idea or science project. This lamp holder features a rolled shell of nickel plated brass mounted on a base with two screw terminals and two pre-drilled holes to mount to a project board. The base diameter is 30mm and the height is 18mm. It holds our 1.2-volt,
2.25-volt

AMM360 is a desktop analog multitester for measuring DC Volt, AC Volt, DC
Current and Resistance. AMM360 can be used as a very sensitive galvanometer and
can show as low as 0.01 DC voltage. AMM360 can also be used to test transistors
and diodes.
